Chronos Veritas (2003)

from the introduction:
This is a very short (about two hours) adventure for RealTime designed as an appetizer and warm-up, a way to get players used to how RealTime works and to work out kinks in the process. It's intended as either the first or, even better, second exposure to RealTime for both player and GM. In essence, it's one extended encounter, but it still offers a taste of almost everything RealTime has to offer, a chance to use just about every rule in the game, and a good exposure to the excitement and time-focused action of RealTime.
